The specific numerals assigned to the elements areprovided solely to aid in the description and not meant to imply anylimitations (structural or functional) on the invention.

It is understood that the use of specific component, device and/orparameter names are for example only and not meant to imply anylimitations on the invention. The invention may thus be implemented withdifferent nomenclature/terminology utilized to describe thecomponents/devices/parameters herein, without limitation. Each termutilized herein is to be given its broadest interpretation given thecontext in which that terms is utilized.

With reference now to FIG. 1, there is depicted a block diagramrepresentation of an electronic device (which is illustrated as, but notlimited to data processing system) configured with a multi-detectionvisual display screen (touch screen). Electronic device 100 comprises atleast one processor or central processing unit (CPU) 101 connected tosystem memory 106 via system interconnect/bus 102. Also connected tosystem bus 102 is I/O controller 115, which provides connectivity andcontrol for input devices, of which pointing device (or mouse) 116 andkeyboard 117 are illustrated. I/O controller 115 is also connected totouch screen interface 112 which is connected to input/output touchscreen display 118. Additionally, a multimedia drive 119 (e.g., CDRW orDVD drive) and USB (universal serial bus) hub 121 are illustrated,coupled to I/O controller. Multimedia drive 119 and USB hub 121 mayoperate as both input and output (storage) mechanisms. Electronic device100 also comprises storage 107, within which data/instructions/code maybe stored. Electronic device 100 further comprises maintenance logic 113which provides a number of maintenance notifications, including one ormore or a combination of the following: (1) a visual highlightingnotification, which involves a visual change in the area (i.e., variousgrades of lighting or dimming); (2) a sound notification, such as anaudio alert; (3) a sensory notification, which may include a completeusage restriction of the screen area; (4) a temperaturenotification/alert, whereby the area heats up or cools down, forexample; and (5) a resolution resizing around the defective area. It isappreciated that the above list is not meant to imply any limitations onthe type of notification that may be executed/implemented.

Electronic device 100 is also illustrated with a network interfacedevice (NID) 125, with which electronic device 100 connects to one ormore servers 133 via access network 130, such as the Internet. In thedescribed embodiments, network 130 is a worldwide collection of networksand gateways that utilize the Transmission Control Protocol/InternetProtocol (TCP/IP) suite of protocols to communicate with one another. Ofcourse, network access may also be provided via a number of differenttypes of networks, such as an intranet, a local area network (LAN), avirtual private network (VPN), or other wide area network (WAN) otherthan the Internet, for example.

Notably, in addition to the above described hardware components ofelectronic device 100, various features of the invention are completedvia software (or firmware) code or logic stored within memory 106 orother storage (e.g., storage 107) and executed by CPU 101. Thus,illustrated within memory 106 are a number of software/firmwarecomponents, including operating system (OS) 108 (e.g., MicrosoftWindows®, a trademark of Microsoft Corp, GNU®/Linux®, registeredtrademarks of the Free Software Foundation and Linus Torvalds, or AIX®,a registered trademark of IBM), maintenance configuration (file) 109,maintenance records (file) 114, Object Recognition Facility 111, andscreen diagnostic and maintenance (SDM) utility 110. In actualimplementation, maintenance configuration (file) 109, maintenancerecords (file) 114, Object Recognition Facility 111, and SDM utility 110may be combined as a single application collectively providing thevarious functions of each individual software component when thecorresponding code is executed by the CPU 101. For simplicity, SDMutility 110 is illustrated and described as a stand alone or separatesoftware/firmware component, which provides specific functions, asdescribed below.

CPU 101 executes SDM utility 110 as well as OS 108, which supports theuser interface features of SDM utility 110. In the illustrativeembodiment, SDM utility 110 generates/provides several graphical userinterfaces (GUI) to enable user interaction with, or manipulation of,the functional features of the utility (110). Among the softwarecode/instructions provided by SDM utility 110, and which are specific tothe invention, are: (a) code for detecting an occurrence of an objectmaking contact with a touch screen display of a computer system; (b)code for characterizing/identifying the object that makes contact withthe screen; and (c) code for initiating a specific maintenance action onthe screen of the computer system. For simplicity of the description,the collective body of code that enables these various features isreferred to herein as SDM utility 110. According to the illustrativeembodiment, when CPU 101 executes SDM utility 110, electronic device 100initiates a series of functional processes that enable the abovefunctional features as well as additional features/functionality, whichare described below within the description of FIGS. 2-3.

Those of ordinary skill in the art will appreciate that the hardware andbasic configuration depicted in FIG. 1 may vary. For example, otherdevices/components may be used in addition to or in place of thehardware depicted. The depicted example is not meant to implyarchitectural limitations with respect to the present invention. Thedata processing system depicted in FIG. 1 may be, for example, an IBMeServer pSeries system, a product of International Business MachinesCorporation in Armonk, N.Y., running the Advanced Interactive Executive(AIX) operating system or LINUX operating system.

In electronic device 100, SDM utility 110 detects contact from an objectat touch screen display 118. SDM utility 110 characterizes the object todetermine whether a maintenance action is required. Object recognitiontechnology may be used to facilitate a characterization of the object.The characterization of the object is important since contact withcertain objects may make touch screen 118 unusable. The types of objectsmaking contact with the touch screen may take various forms which mayinclude the following non-exhaustive list: (1) finger(s); (2) hand(s);(3) paper; (4) mist from the breath of a human being; (5) liquid; and(6) food. Sometimes multiple occurrences of contact by a particularobject (e.g., a user's hands/fingers) with the touch screen are requiredto activate a maintenance action. However, a single occurrence ofcontact by another object (e.g., liquid) with the touch screen may beenough to activate a maintenance notification and/or action. Forexample, a drink/liquid spilling (see FIG. 2B) on touch screen 118 maycreate a greater level of urgency (i.e., may be assigned a higher levelof maintenance priority) than bread crumbs coming into contact withtouch screen 118. Furthermore, in this case, perhaps only one occurrenceof a contact of this nature may be required to initiate a maintenanceaction. Thus, SDM utility 110 characterizes and distinguishes varioustypes of object contact. SDM utility 110 refers to configurationrecord(s) 109 to determine the type of maintenance action required andthe schedule of the action. For example, in the case of an objectcharacterized as a “liquid spill”, the maintenance action may be to“clean the entire touch screen surface” and the schedule may be“immediately”.

In electronic device 100, the maintenance notification (and/ormaintenance action) may take various forms. As utilized herein the termnotification and action may refer to a same activity or differentactivity of the SDM utility 110. That is, a notification may beconsidered an action, and vice versa, while some actions are notnotifications. For simplicity, the term “maintenance action” is used torepresent both a notification and an action taken by the SDM utility110. In particular, the maintenance action may be a combination of anyof the following and may not be limited to: (1) a visual change in thearea (i.e., various grades of lighting or dimming); (2) an audio alert;(3) a complete usage restriction of the screen area; (4) a temperaturealert (i.e. the area heats up or cools down); and (5) a resolutionresizing around the defective area. Multiple usage of the screenincreases the likelihood for maintenance due to normal wear-and-tear andalso creates a risk factor for germs/infection. Upon detection that thearea of the screen is unclean as determined by a preset threshold levelof cleanliness, the computer cross-references the user's prioritysetting for a cleaning action. A cleaning action may not be scheduledbased on a number of factors which may include priority, time of day,etc.

SDM utility 110 may initiate maintenance action in the form of a screenprotection mechanism. This mechanism may be executed by the computerbased on certain configurable conditions. To avoid integration of thismechanism within the touch screen surface, SDM utility 110 may initiatecommunication with the protection mechanism via blue-tooth capability.Blue-tooth capability enables communication between the protectionmechanism device and the computer in order to provide location detailsof the affected area to the protection mechanism device. SDM utility 110may allow the protection mechanism to be applied to the full surfacearea. Alternatively, SDM utility 110 may indicate that alayered/sectional screen protection to specific areas is desired. Thescreen protection mechanism may include the following: (1) a transparentfilm to be applied to or removed from the surface; and (2) a wipermechanism that dispenses cleaning material across the surface.

SDM utility 110 may employ an interaction or idleness level as a cue forscheduling a maintenance action on the screen surface. Based on thelevel of interaction or idleness, a time of day, ambient light ormovement around the screen surface, a maintenance cycle may beinitiated/scheduled.

FIG. 2A illustrates a touch screen display with multiple interactingusers, according to one embodiment of the invention. Object-screensystem 200 comprises touch screen display 118 with interactinguser(s)/object(s) 201. In object-screen system 200, SDM utility 110 iscapable of characterizing/identifying the object as a finger/hand. SDMutility 110 may further characterize “surface” characteristics of theobject, such that a finger with grease is characterized differently fromone with sweat (e.g., a sweaty or moist hand/finger). SDM utility 110 isable to distinguish between various types of contact in order todetermine scheduling based on a configured priority and to select themost appropriate maintenance action. In one embodiment, for example, SDMutility 110 may employ Object Recognition Facility 111 to facilitate thecharacterization of object 201.

FIG. 2B is a block diagram of a multi-detection touch screenillustrating factors affecting the level of cleanliness of the screenand an example list of steps provided by SDM utility 110 to assist auser in resolving a screen maintenance issue, according to embodimentsof the invention. Screen example 210 comprises touch screen 118.Disposed on touch screen 118 is liquid spill 211. A low pixel resolutionarea 212 of visual display on touch screen 118 is also illustrated. Asprovided within screen example 210, low resolution area 212 illustratesa section of the touch screen where clarity has been reduced.Additionally, a list with cleaning steps illustrated as maintenance list213 is displayed on touch screen 218.

One application of low pixel resolution area 212 involves SDM utility110 triggering an adjustment to the brightness, contrast, or degradationof screen resolution (bits per pixel) in an affected screen area. Forexample, with continual usage of the screen, SDM utility 110 may allowthe area to continually change (degrade) in clarity. Thus, SDM utility110 provides a visual indication of the level of dirtiness of that areaof the screen 118, and responds by causing the area of the screen 118 topartially lose clarity. In extreme situations, SDM utility 118 may fullyrestrict visual display at a portion of the screen.

SDM utility 110 may alert the user to a possible problem (e.g.,defective pixels, opaque/unclean section of the screen) with the surfacescreen via a constant indicator on or around the area affected. Theconstant indicator may include: (1) a visual effect such as highlightingor a display of icons, or arrows, on the screen; (2) a touch sensorymechanism by which the affected area becomes warmer or cooler to thetouch; and (3) an audio sensory mechanism in which a sound becomeslouder when a user/object gets within a certain proximity of theaffected area.

SDM utility 110 may discover that pixels on the screen may be defective,after a maintenance action, for example. Consequently, SDM utility 110may initiate a maintenance cycle to determine whether the pixel isactually “stuck” versus “dead” and then initiate the appropriate fix. Asa maintenance action, SDM utility 110 may also provide temporary lowresolution (212) of visual display on touch screen 118.

FIG. 3 is a flow chart illustrating a method by which the aboveprocesses of the illustrative embodiments are completed. Although themethod illustrated in FIG. 3 may be described with reference tocomponents shown in FIGS. 1-2, it should be understood that this ismerely for convenience and alternative components and/or configurationsthereof can be employed when implementing the various methods. Keyportions of the methods may be completed by SDM utility 110 executingwithin electronic device 100 (FIG. 1) and controlling specificoperations of/on electronic device 100, and the methods are thusdescribed from the perspective of either/both SDM utility 110 and themulti-touch screen (118).

The process of FIG. 3 begins at initiator block 301 and proceeds toblock 302, at which SDM utility 110 initiates an active mode. SDMutility 110 continuously monitors screen activity and initiatesactivities based on an external trigger (e.g., human contact) orinternal triggers as a result of a pre-determined configuration.Furthermore, all user and computer system interaction via a touch screenproceeds without interruption by SDM utility 110.

At block 303, SDM utility 110 detects contact of an object(s) with thetouch screen. SDM utility 110 initiates procedures to characterize theobject, as shown at block 304. These procedures which reveal theproperties of the object may include a number of the following: (1) aweight measurement; (2) a temperature measurement; (3) a location of theobject; (4) an opacity level of the object; (5) further procedures(which may generate visual images/photographs of objects coming intocontact with the touch screen, for example) to obtain data as inputs toan object recognition facility; and (6) multiple applications of the(measurement) procedures at various intervals in order to record changesin the object's properties over time. At block 305, SDM utility 110identifies/characterizes the object based on the procedures to obtainthe object characteristics. SDM utility 110 may determine whether theobject is a liquid or a solid, for example, based on an identificationof a set of properties of the object. The identification of the physicalstate may require multiple executions of a number of the precedingprocedures. For example, a first measurement taken at one time intervaland a second measurement taken subsequently may reveal the dynamicnature of a liquid, the location of which may change/expand as theliquid spreads across the touch screen. In addition, SDM utility 110 maybe able to predict the manner in which the liquid spreads across thescreen based on a computed viscosity of the liquid (obtained via theprocedures/measurements).

At block 306, SDM utility 110 records, in a maintenance results file inthe computer system, the occurrence of the contact of thecharacterized/identified object with the touch screen. Thus, SDM utility110 is able to track a particular type of occurrence of object contactand provide a determination of the ability of the contact by the objectwith the touch screen to affect the level of screen cleanliness, basedon the object characterization.

In addition to the measurement/maintenance procedures initiated by anexternal trigger, at a preset time period(s), SDM utility 110 initiatesa number of maintenance screen checks, as shown at block 307. The timingof the maintenance checks are preset by configuration settings in astored maintenance configuration file. The maintenance screen checks maybe executed to determine a cleanliness level of the screen. A level ofcleanliness may be determined by a reading(s) obtained via opacitysensors. The results of the maintenance checks are also recorded in theresults file.

At block 308, SDM utility 110 performs an analysis to determine whethera maintenance action on the touch screen is required by utilizing anumber of the following: (1) object characterization; (2) maintenancecheck results; and (3) maintenance configuration file(s). The objectcharacterization and the maintenance check results may be stored in themaintenance results file(s). At decision block 309, SDM utility 110determines whether a maintenance action(s) is required, based on theanalysis results. If, at block 309, SDM utility 110 determines that amaintenance action(s) is required, the process moves to block 310, atwhich SDM utility 110 determines the specific type of maintenanceaction(s) required based on the configuration file(s) and/or maintenanceresults file. At block 311, SDM utility 110 enters a maintenance modeand initiates a specific maintenance action. In one embodiment, list 213may be displayed on the visual display touch screen to provide amaintenance staff/user with a list of steps for completing maintenanceaction(s).

The maintenance action may take various forms and may be a combinationof a number of other maintenance actions. These maintenance actions areoutlined in the description of the figures. Once the maintenance actionis completed, as shown at block 312, active mode resumes (i.e., thesystem returns to the normal state of operation), and the processreturns to block 302 for continuous monitoring.

In the flow charts above, one or more of the methods are embodied as acomputer program product in a computer readable medium or containingcomputer readable code such that a series of steps are performed whenthe computer readable code is executed on a computing device. In someimplementations, certain steps of the methods are combined, performedsimultaneously or in a different order, or perhaps omitted, withoutdeviating from the spirit and scope of the invention. Thus, while themethod steps are described and illustrated in a particular sequence, useof a specific sequence of steps is not meant to imply any limitations onthe invention. Changes may be made with regards to the sequence of stepswithout departing from the spirit or scope of the present invention. Useof a particular sequence is therefore, not to be taken in a limitingsense, and the scope of the present invention is defined only by theappended claims.

As will be further appreciated, the processes in embodiments of thepresent invention may be implemented using any combination of software,firmware, or hardware. As a preparatory step to practicing the inventionin software, the programming code (whether software or firmware) willtypically be stored in one or more machine readable storage mediums suchas fixed (hard) drives, diskettes, optical disks, magnetic tape,semiconductor memories such as ROMs, PROMs, etc., thereby making anarticle of manufacture (or computer program product) in accordance withthe invention.
